HAT-PIN.

SPECIFICATION forming' part of Letters Patent No. 710,349, dated September 30, 1902.

Application filed June l2, 1902. Serial No. 111,292. KNO model.)

To all whom, it nto/y concern.-

Beit known that I, JOHN VIESEN, a citizen of the United States of America, residing at Braddock, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in l-Iat-Pins, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain-new and useful improvements in hat-pins, and has for its object a device of this character which may be readily inserted into a hat and engage the same, so that an accidental displacement of the hat is practically impossible.

My invention has for its further object a device of this character which may be 'of simple and economical construction, efcient in its operation, and cheap to manufacture.

With the above and other objects in view the invention consists in the novel construction, combination, and arrangement of parts, to be hereinafter more fully described, and specifically pointed out in the claim.

In describing the invention in detail reference is had to the accompanying drawings, forming a part of this specification, and wherein like numerals of reference indicate like parts throughout the several views,in which- Figure l is a longitudinal sectional View of the improved device. Fig. 2 is a like View ofthe lower end of the same considerably enlarged and showing in dotted lines the normal position assumed by the forks.

In carrying the invention into practice I preferably employ the tube 1, of equal diameter throughout, which at its rear end is threaded, as at 2, and receives the conicalshaped member 3, provided with a sharppointed end in order to permit the member being easily inserted in to the hat. This mem'- ber, as will be noted, is interiorly threaded, as at 4, and engages the threads on the lower end of the tube l and is further provided with diametrical oppositely arranged elongated slots 5, of a slight Width. At itsfront end this tube l is flared, as at 6, and is interiorly threaded to receive the head 7 of the pin, this head being threaded in order to engage in the threads of the flared portion of the tube 1. This head :member is also provided with diametrical oppositely-arranged elongated slots S, in which operates the head 9 of the rod l0, the head 9 being received within the head member of the tube and carrying oppositelydisposed guides 1l, the latter extending through the previously mentioned slots S. Interposed between the head 9 of the rod and the cap 12, which may, as shown, be threaded onto the end of the head member of the tube, is a'spiral spring 13, which normally presses outwardly against the head 9 and secures the same, ltogether with the forks of the rod, in the position shown in dotted lines in Fig. 1. The forks (designated by the numerals 14) are preferably of an arc shape,decreasin g in width toward their engaging ends, the rear ends of the forks being pivoted, as at 15, to the lower end of the rod 10,these forks operating through the slots 5 and when in their retracted position have their engaging ends resting against the end walls formed by the slots 5 in order that when the head 9 is released from its retracted position the ends of these forks will ride and be guided by the end walls formed by the slot 5, which will be apparent from inspection of Fig. 2 of the drawings.

As previously stated, when the device is in its operative position it assumes the position indicated by the dotted lines in the several figures of the drawings, and when it is desired to employ the pin the guides 11 are grasped by the fingers, and the rod l0 is thereby forced into its retracted position, which will cause the fork members to assume the position shown in dotted lines of the several figures. The pointed end of the conical member may then be readilyinserted through the hat, and since the forks are located within the interior `of said conical member they will of course offer no obstruction to the free passage ofthe conical member through the hat. After the pin has been placed in the desired position the guides 11 are released, and by reason of the tension of the spring the rod, together with the forked member, will be forced in position, as shown in dotted lines, which will prevent any accidental disengagement, of the pin from the latter.

The above illustrates the most practical embodiment of my invention, though slight changes and alterations may be made inthe IOO details -of construction and combination of parts Without departing from the general spirit and scope of the invention.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-d A device ofthe type set forth, consisting of a tube having a hollow conical-shaped portion threaded to its lower end with oppositelyarranged elongated slots arranged therein, a rod having arc-shaped forks pivoted to its ends, said forks having their ends engaging the end Walls formed by the said slots, the opposite end of said tube being iiared, a head member threaded Within said flared end and
